<1. System Configuration Example>

FIG. 1 illustrates a configuration example of one embodiment of an information processing system to which the present technology is applied.

An information processing system 1 FIG. 1 is a system which includes a sensor device 11, a smartphone 12, a server 13, and a personal computer (PC) 14 and performs predetermined data processing using a sensor signal output by the sensor device 11. The smartphone 12, the server 13, and the PC 14 are connected to one another via a network 15 such as the Internet, a telephone network, a satellite communication network, a local area network (LAN), a wide area network (WAN), for example.

The sensor device 11 is attached to a predetermined portion (for example, a grip end) of a racket 41 and outputs the sensor signal capable of calculating shot data when a user hits a ball 42 using the racket 41 (hereinafter also referred to as shot data) to the smartphone 12.

The sensor device 11 is provided with, for example, a vibration sensor, and outputs the sensor signal indicating vibration (impact) when the user hits the ball 42 using the racket 41 to the smartphone 12. Also, the sensor device 11 is provided with, for example, an acceleration sensor, an angular speed sensor, a geomagnetic sensor and the like (for example, a nine-axis motion sensor) and the like and outputs the sensor signal indicating acceleration, an angular speed, inclination and the like of the racket when the user hits the ball 42 using the racket 41 to the smartphone 12.

Meanwhile, the sensor signal and a control signal exchanged between the sensor device 11 and the smartphone 12 are transmitted using near field communication such as Bluetooth (registered trademark) and wireless local area network (LAN), for example.

The smartphone 12 receives the sensor signal transmitted from the sensor device 11 using the near field communication and stores the same in an internal memory. In addition, the smartphone 12 analyzes the received sensor signal, thereby converting the same into the shot data indicating information of a shot when the user hits the ball 42 using the racket 41. Then, the smartphone 12 transmits the converted shot data of the user to the server 13 via the network 15 together with user information.

Meanwhile, the smartphone 12 is an example of a device which performs processing of obtaining the sensor signal transmitted from the sensor device 11, converting the same into the shot, data, and transmitting the same to the server 13. Not only the smartphone 12 but also an information processing device such as a tablet terminal and a PC may perform processing similar to that of the smartphone 12 according to this embodiment.

FIG. 2 illustrates the user information and the shot data transmitted from the smartphone 12 to the server 13 in detail.

The user information includes a user ID for identifying the user who plays tennis, position information indicating a location of the user, and time information indicating current date and time. The user information may be added for each shot data or may be added for each series of shot data including a plurality of shot data. The position information is obtained from, for example, a global positioning system (GPS) receiver included in the smartphone 12. The time information is obtained from, for example, a clock included in the smartphone 12. Meanwhile, it is also possible that the sensor device 11 itself is provided with the GPS receiver and the clock, and the position information and the time information are obtained from the sensor device 11.

The shot data includes a hitting position, a ball speed, a swing speed, a ball spin, and a swing type. The shot, data is generated in shot (ball hit) unit.

The hitting position indicates a hitting (contact) position of the ball 42 when the ball 42 is hit by the racket 41. The hitting position is indicated by, for example, an area number of an area obtained by dividing a face surface of the racket 41 into a grid pattern.

The ball speed is a speed (initial speed) of the ball 42 when the ball 42 is hit by the racket 41 and is expressed in km/h or mph.

The swing speed is a speed of the racket 41 when the ball 42 is hit by the racket 41 and is expressed in km/h or mph.

The ball spin is an amount of rotation of the ball 42 generated when the ball 42 is hit by the racket 41 and is expressed by an integer value of 21 steps from −10 to +10.

The swing type is a type of swing when the ball 42 is hit by the racket 41; it is discriminated as any one of a forehand slice, a forehand spin/flat, a forehand volley, a back hand slice, a back hand spin/flat, a back hand volley, a smash, and a serve as illustrated in FIG. 2.

Each item of the shot data may be discriminated by extracting a statistical feature amount such as a frequency characteristic, an average, a variance, a minimum value, and a maximum value from time series data of various sensor signals transmitted from the sensor device 11 and comparing the same with a feature value of each item prepared in advance, for example. Alternatively, for discriminating each item of the shot data, a non-rule based method of forming a discriminating parameter from data by machine learning such as a neural network, a support vector machine (SVM), a k nearest neighbor discriminator, and Bayesian classification, for example, may also be used.

With reference to FIG. 1 again, the server 13 stores the user information and the shot data transmitted from the smartphone 12 of each user who is a user of the information processing system 1 in an internal database. The position information indicating the location of the user is converted into country information to be stored in the database. Then, in response to a request from the PC 14, the server 13 transmits the user information and the shot data of each user stored in the database to the PC 14.

Meanwhile, although it is assumed that the smartphone 12 performs processing of discriminating the shot data from the sensor signal and transmits the user information and the shot data to the server 13 as described above in this embodiment, it is also possible that the sensor signal output from the sensor device 11 is directly transmitted to the server 13 via the smartphone 12 and the server 13 performs the processing of discriminating the shot data and stores the same in the database. That is, the processing of discriminating the shot data from the sensor signal may be performed by either the smartphone 12 or the server 13.

The PC 14 executes shot data display control processing of accessing the server 13 via the network 15, obtaining the user information and the shot data of a large number of users accumulated in the database of the server 13, and generating a processed image in which the obtained enormous shot data of a large number of users are visualized so as to be visually easily understood. The PC 14 outputs image control data of the processed image generated by the shot data display control processing to a display 51 and allows the display 51 to display the processed image.

Meanwhile, the PC 14 is an example of a device which performs the shot data display control processing of obtaining and visualizing the data accumulated in the server 13. An information processing device such as a smartphone and a tablet terminal may also perform the processing similar to that of the PC 14 in place of the PC 14.

In the information processing system 1 configured as described above, the shot data of the users of the countries around the world are collected in the server 13 to be accumulated in the database. The user who is the player who attaches the sensor device 11 to the racket 41 and plays tennis operates the PC 14. The PC 14 executes the shot data display control processing according to operation of the user. By this shot data display control processing, the shot data of a large number of users accumulated in the server 13 are obtained and the processed image is generated to be displayed on the display 51. The user may look at the processed image displayed on the display 51 and compare the same with the user's own shot data stored in the smartphone 12, for example.

In the following, the shot data display control processing of obtaining the user information and the shot data of a large number of users accumulated in the database of the server 13, visualizing the same so as to be visually easily understood, and presenting the same to the user performed by the PC 14 is described in detail.

<2. Functional Block Diagram>

FIG. 3 illustrates a functional block diagram of the server 13 and the PC 14 regarding the shot data display control processing.

The server 13 includes at least a storage unit 81, a processing unit 82, and a communication unit 83.

The storage unit 81 includes a database including a hard disk drive (HDD), a semiconductor memory and the like, and stores the user information and the shot data transmitted from the smartphone 12 of each user, for example. As described above, the position information transmitted from the smartphone 12 is converted into the country information and stored in the database. Meanwhile, in the following description, the user information and the shot data are collectively referred to as play data, and each item of the user information and the shot data forming the play data is also referred to as a data attribute.

A program which controls operation of an entire server 13, user registration information of the user who accesses the server 13, and the like are also stored in the storage unit 81. The user registration information includes, for example, a user registration ID and a password used when accessing the server 13, sex, age, country information and the like. The user registration ID and the user ID may be the same.

The processing unit 82 executes processing of allowing the database of the storage unit 81 to store the play data of each user transmitted from the smartphone 12. Also, in response to the request from the PC 14, the processing unit 82 executes processing of transmitting the play data stored in the database to the PC 14. The processing unit 82 includes a processor such as a central processing unit (CPU), for example.

The communication unit 83 receives a command and data transmitted from the smartphone 12 and the PC 14 and supplies them to the processing unit 82. Also, the communication unit 83 transmits the command and data supplied from the processing unit 82 to the smartphone 12 and the PC 14.

The communication unit 83 is a communication interface including a communication device and the like for connecting to the wired or wireless network 15. The communication unit 83 may be a wireless local area network (LAN) compliant communication device, a long term evolution (LIE) compliant communication device, or a wire communication device which performs communication by wire.

The PC 14 includes at least a communication unit 91, an input unit 92, a processing unit 93, an output unit 94, and a storage unit 95.

The communication unit 91 receives the command and data transmitted from the server 13 and supplies them to the processing unit 93. Also, the communication unit 91 transmits the command and data supplied from the processing unit 93 to the server 13. The communication unit 91 is a communication interface including a communication device and the like for connecting to the network 15 as is the case with the communication unit 83 of the server 13. The communication unit 91 may also communicate with devices other than the server 13.

The input unit 92 includes, for example, a touch panel provided on a display, an operation button, a controller, a mouse and the like, accepts an operation input by the user, and supplies the same to the processing unit 93. The input unit 92 may also include a microphone for accepting user's voice as the operation input, a camera or a sensor for accessing user's gesture as the operation input, and the like.

The processing unit 93 executes the shot data display control processing. That is, the processing unit 93 requires the server 13 of necessary play data on the basis of the operation of the user supplied from the input unit 92, generates the processed image obtained by processing the play data obtained from the server 13 such that the user may easily understand, and supplies the image control data thereof to the output unit 94.

For example, the processing unit 93 obtains the play data of all the users stored in the server 13 and generates the processed image. For example, the processing unit 93 obtains only a part of the play data such as play data of the user belonging to a certain country and play data of a predetermined date from the server 13 and generates the processed image.

The processing unit 93 includes a processor such as a central processing unit (CPU), for example, and executes predetermined processing such as the shot data display control processing by execution of a program stored in the storage unit 95.

<3, Processed Image Example (1)>

FIG. 4 illustrates an example of the processed image generated by the shot data display control processing performed by the processing unit 93 and displayed on the display 51.

The processed image 201 illustrated in FIG. 4 is the processed image generated by obtaining only play data of users in Italy out of the play data stored in the server 13.

In a right side area of the processed image 201, a particle display area 212 for displaying a particle stereoscopic image in which respective shot data are stereoscopically represented using particles 211 on the basis of the play data obtained from the server 13 is arranged. The particle 211 represents a granular, a particulate, or a spherical shape. One particle 211 corresponds to the shot, data of one shot, and at least the hitting position, ball speed, swing speed, ball spin, and swing type of one shot are associated with one particle 211. The particle stereoscopic image is described later in detail with reference to FIG. 5.

In the particle display area 212, a cursor 213 used when the user selects a desired particle 211 is also displayed. The cursor 213 moves according to the operation of the user in the input unit 92.

Meanwhile, the particle display area 212 is illustrated for the sake of convenience. For example, an entire area of the processed image may become the particle display area 212 though some of the particles 211 are also distributed outside the particle display area 212 in a processed image 301 in FIG. 16 and a processed image 321 in FIG. 18 to be described later.

In a left side area of the processed image 201, a country name display part 221 for displaying a country name of the displayed play data and a data number display part 222 for displaying the number of displayed shot data are displayed.

“Italy” is displayed in the country name display part 221 of the processed image 201, indicating that the shot data of the processed image 201 are the shot data of the users in Italy.

In the data number display part 222 of the processed image 201, “86552” is displayed, indicating that the number of data of the shot data of the users in Italy is 86552. Since one particle 211 of the particle stereoscopic image corresponds to one shot data, the number of particles 211 displayed in the particle display area 212 is also 86552.

There are two columns under the data number display part 222 in which a player number display part 231, an average ball speed display part 232, an average swing speed display part 233, and an average ball spin display part 234 are arranged in a left column. In a right column, a user ID display part 241, a ball speed display part 242, a swing speed display part 243, and a ball spin display part 244 are arranged.

The number of players of the shot data displayed in the particle display area 212 is displayed in the player number display part 231. That is, the player number display part 231 displays to how many people the shot data displayed in the particle display area 212 belong.

In the average ball speed display part 232, an average value of the ball speeds for all the shot data displayed in the particle display area 212 is displayed. Therefore, in the processed image 201 in FIG. 4, the average value of the ball speeds of all the players in Italy is displayed.

In the average swing speed display part 233, an average value of the swing speeds for all the shot data displayed in the particle display area 212 is displayed. Therefore, in the processed image 201 in FIG. 4, the average value of the swing speeds of all the players in Italy is displayed.

An average value of the ball spins for all the shot data displayed in the particle display area 212 is displayed in the average ball spin display part 234. Therefore, in the processed image 201 in FIG. 4, the average value of the ball spins of all the players in Italy is displayed.

In the user ID display part. 241, the user ID of the particle 211 selected by the cursor 213 in the particle display area 212 is displayed. That is, in the user ID display part 241, person to whom the shot data selected by the cursor 213 belongs is displayed.

In the ball speed display part 242, a value of the ball speed of the particle 211 selected by the cursor 213 in the particle display area 212 is displayed.

In the swing speed display part 243, a value of the swing speed of the particle 211 selected by the cursor 213 in the particle display area 212 is displayed.

In the ball spin display part 244, a value of the ball spin of the particle 211 selected by the cursor 213 in the particle display area 212 is displayed.

Next, with reference to FIG. 5, the particle stereoscopic image displayed in the particle display area 212 is described.

The processing unit 93 generates the particle stereoscopic image in which the particles 211 corresponding to respective shot data to be displayed are distributed on a side surface of a conical shape and displays the same in the particle display area 212 as illustrated in A of FIG. 5. An axis in a height direction of the conical shape corresponds to the ball speed of each shot data, and it is arranged in a position closer to an apex of the conical shape as the ball speed is faster, and arranged in a position closer to a bottom surface of the conical shape as the ball speed is slower.

B of FIG. 5 is a plan view of the particle stereoscopic image in the conical shape as seen from above.

The swing type of each shot data to be displayed is classified into any one of eight types; the forehand slice, the forehand spin/flat, the forehand volley, the back hand slice, the back hand spin/flat, the back hand volley, the smash, and the serve.

In a case where the particle stereoscopic image in the conical shape is seen from above, the particle stereoscopic image is a pie chart (circular chart) in which the particles 211 are distributed for each swing type to have an area corresponding to a ratio of each swing type with respect to the number of all the data to be displayed.

For example, in a case of color display, the particles 211 are drawn in different colors for each swing type, and in a case of monochrome display (gray display), they are drawn in different gray values for each swing type. This makes it possible to understand the difference in swing type and the ratio of each swing type at a glance. In the example in B of FIG. 5, it may be understood at a glance that the forehand spin/flat data is large.

In addition, since the axis in the height direction of the conical shape corresponds to the ball speed, when seen as the pie chart, the particle 211 is arranged in a position closer to the center of the circle as the ball speed is faster and arranged in a position closer to an outer periphery of the circle as the ball speed is slower. As a result, for example, the tendency of the ball speed for each swing type may be understood at a glance.

<4. Processed Image Example (2)>

FIG. 6 illustrates another example of the processed image generated by the processing unit 93.

A processed image 261 illustrated in FIG. 6 is the processed image generated by obtaining only play data of the users in New Zealand out of the play data stored in the server 13.

Therefore, “New Zealand” is displayed in the country name display part 221, and “21692” which is the number of shot data of the users in New Zealand is displayed in the data number display part 222.

In addition, although not described individually, the value of each of the player number display part 231, the average ball speed display part 232, the average swing speed display part 233, the average ball spin display part 234, the user ID display part 241, the ball speed display part 242, the swing speed display part 243, and the ball spin display part. 244 corresponds to the shot data of the users in New Zealand.

Then, in the particle display area 212, the particle stereoscopic image in which the particles 211 corresponding to 21692 shot data of the users in New Zealand are distributed in the conical shape is displayed.

Herein, the number of shot data of the processed image 261 of New Zealand in FIG. 6 is 21692, which is approximately ¼ of the number of data 86552 of the processed image 201 of Italy illustrated in FIG. 4; however, density of the particles 211 in the particle stereoscopic image displayed in the particle display area 212 is substantially the same in the processed image 261 of New Zealand and the processed image 201 of Italy.

In other words, although the number of shot data of the processed image 261 of New Zealand in FIG. 6 is approximately ¼ of the number of data of Italy illustrated in FIG. 4, the distribution in the particle stereoscopic image in FIG. 6 is not sparser than that in the particle stereoscopic image in FIG. 4, and this gives an impression that similar number of particles 211 are distributed. This is because the processing unit 93 adjusts a size of the particle 211 according to the number of shot data.

FIG. 7 illustrates a processed image 281 of New Zealand in which the particle size of the processed image 261 of New Zealand in FIG. 6 is set to be the same as the particle size of the processed image 201 of Italy illustrated in FIG. 4 as a comparative example.

Comparing the distribution of the particles 211 of the swing type “forehand spin/flat” around the cursor 213 between the processed image 201 in FIG. 4 and the processed image 261 in FIG. 6, the particles are distributed more in an upper part of the side surface of the conical shape in the processed image 261 of New Zealand in FIG. 6, and it is understood that there are more people with a faster ball speed of the swing type “forehand spin/flat” in New Zealand than in Italy in FIG. 4.

On the other hand, comparing the processed image 281 in FIG. 7 with the processed image 201 in FIG. 4 in which the particle size is set to be the same irrespective of the number of data, the density of the particles 211 in the upper part of the side surface of the swing type “forehand spin/flat” in FIG. 7 is approximately the same as the density of the particles 211 in the upper part of the side surface of the swing type “forehand spin/flat” in FIG. 4, so that there is no impression that there are more people with a faster ball speed of the swing type “forehand spin/flat” in New Zealand.

In this manner, by adjusting the particle size according to the number of data of the shot data to be displayed, data comparison becomes easy regardless of the number of data.

<5. Particle Size Determination Processing Flow>

Particle size determination processing by the processing unit 93 is described with reference to a flowchart in FIG. 8.

First, at step S1, the processing unit 93 obtains the shot data to be displayed from the server 13. For example, in a case where the user operates the input unit 92 to display the data of the player in Italy, the processing unit. 93 requires the server 13 of the play data of the player in Italy via the communication unit 91 and obtains the play data (user information and shot data) transmitted from the server 13 in response to the request.

At step S2, the processing unit 93 calculates a particle size Psize of the particle 211 drawn in the particle display area 212 by using following equation (1). Psize=C*L/(number of data)^(1/3)  (1)

In equation (1), C represents a predetermined constant, and L represents a length of each side of a three-dimensional space which may be displayed in the particle display area 212 as illustrated in FIG. 9. The length L of each side is appropriately determined in accordance with an area size of the particle display area 212, and the constant C serves as an adjustment coefficient for adjusting the particle size Psize and may be appropriately set on a setting screen and the like. The number of shot data obtained from the server 13 is input to the “number of data” in expression (1).

At step S3, the processing unit 93 determines whether the calculated particle size Psize is smaller than a lower limit value PSI determined in advance.

At step S3, in a case where it is determined that the calculated particle size Psize is smaller than the lower limit value PS1 determined in advance, the procedure shifts to step S4, and the processing unit 93 changes the particle size Psize to the lower limit value PS1 and the procedure shifts to step S7.

On the other hand, in a case where it is determined at step S3 that the calculated particle size Psize equal to or larger than the lower limit value PS1 determined in advance, the procedure shifts to step S5, and the processing unit 93 determines whether the calculated particle size Psize is larger than an upper limit value PS2 determined in advance.

At step S5, in a case where it is determined that the calculated particle size Psize is larger than the upper limit value PS2 determined in advance, the procedure shifts to step S6, and the processing unit 93 changes the particle size Psize to the upper limit value PS2 and the procedure shifts to step S7.

On the other hand, in a case where is determined at step S5 that the calculated particle size Psize is equal to or smaller than the upper limit value PS2 determined in advance, the procedure shifts to step S7. As a result, in a case where the calculated particle size Psize is within a range from the lower limit value PS1 to the upper limit value PS2, the particle size Psize calculated at step S2 is adopted as it is. The processing at steps S2 to S6 is performed on all the shot data to be displayed obtained at step S1.

At step S7, the processing unit 93 generates the particle stereoscopic image in which the particles 211 corresponding to the respective shot data to be displayed are distributed in the conical shape with the determined particle size Psize.

As described above, in the particle size determination processing, the particle size Psize is determined according to the number of shot data to be displayed and a space size of the particle display area 212, so that it is possible to display in unified density of the particles 211 regardless of the number of data. As a result, it becomes possible to easily compare even in a case where the number of data to be displayed is significantly different, and enormous data may be displayed so as to be easily understood.

<6. Processed Image Example (3)>

Next, another feature of the processed image displayed by the shot data display control processing of the processing unit 93 is described.

FIG. 10 illustrates an example of the processed image generated by the shot data display control processing performed by the processing unit 93 and displayed on the display 51.

The processed image 261 illustrated in FIG. 10 is an image of the particle stereoscopic image in the particle display area 212 of the processed image 261 of New Zealand illustrated in FIG. 6 from another viewpoint as seen from above as illustrated in B of FIG. 5. The user may change the viewpoint of the particle stereoscopic image in the particle display area 212, for example, by operating the mouse or controller of the input unit 92.

The processing unit 93 changes the display of the particle stereoscopic image in the particle display area 212 depending on whether or not the user performs data selection operation of selecting a predetermined particle 211 of the particle stereoscopic image. The data selection operation is defined, for example, by operation of specifying a predetermined particle 211 of the particle stereoscopic image displayed in the particle display area 212 with the cursor 213 and pressing a predetermined operation button.

As illustrated in FIG. 11, assuming that the particle size Psize of each particle 211 determined in the particle size determination processing in FIG. 8 is set to a minimum size Psize1 and a size Ak times (Ak>0) the minimum size psize1 is set to a maximum size psize2, in a case where the user does not perform the data selection operation, the processing unit 93 changes the particle size Psize of each particle 211 according to lapse of time between the minimum size psize1 and the maximum size psize2.

Herein, a magnification coefficient Ak for determining the maximum size psize2 when changing the particle size Psize according to the lapse of time is a value proportional to a value of a predetermined data attribute of the play data.

In this embodiment, the magnification coefficient. Ak for determining the maximum size psize2 is set to a value proportional to the value of the swing speed being one of the predetermined data attributes of the play data. As a result, the processing unit. 93 sets the particle size Psize of each particle 211 determined by the particle size determination processing in FIG. 8 as the minimum size psize1 and changes the particle size Psize such that amplitude (difference between the minimum size Psize1 and the maximum size Psize2) is larger as the value of the swing speed of the particle 211 is larger. Meanwhile, timing of amplitude change of the particle size Psize is different for each particle 211 (the amplitude change of each particle 211 is not synchronized).

On the other hand, in a case where the user performs the data selection operation and a predetermined particle 211 is being selected, the processing unit 93 displays the particle stereoscopic image which emphasizes the particle 211 having the same data attribute as that of the data of the selected particle 211.

Specifically, as illustrated in FIG. 12, the processing unit 93 displays the particle stereoscopic image obtained by multiplying the particle size Psize by C1 (C1>1) for the particle 211 having the same attribute as that of the data selected particle 211 and by multiplying the particle size Psize by C2 (C2<1) for the particle 211 having the attribute different from that of the data selected particle 211.

FIG. 13 illustrates the processed image 261 changed during the data selection by the data selection operation performed by the user from a state of the processed image 261 illustrated in FIG. 10.

In this embodiment, the user ID is adopted as the same attribute as that of the data selected particle 211. Therefore, the particle stereoscopic image displayed in the particle display area 212 of the processed image 261 in FIG. 13 is the image obtained by enlarging (multiplying by C1) the particle size Psize as for the particle 211 having the same user ID as the user ID of the data selected particle 211, and by reducing (multiplying by C2) the particle size Psize as for the particle 211 having the user ID different from the user ID of the data selected particle 211. In this manner, by emphasizing the particles 211 having the same data attribute, it is easy for the user to discriminate the data having the same data attribute.

<7. Data Selection Display Change Processing Flow>

Data selection display change processing by the processing unit 93 is described with reference to a flowchart in FIG. 14.

First, at step S21, the processing unit 93 executes the above-described particle size determination processing in FIG. 8, thereby determining the particle size Psize of the particle 211. Therefore, the particle size determination processing in FIG. 8 is executed as a part of the data selection display change processing.

At step S22, the processing unit 93 determines whether the user performs the data selection operation to specify a predetermined particle 211 of the particle stereoscopic image displayed in the particle display area 212 with the cursor 213 to press the predetermined operation button.

At step S22, in a case where it is determined that the data selection operation is performed, the procedure shifts to step S23, and the processing unit 93 multiples the particle size Psize by C1 (C1>1) as for the particle 211 having the same data attribute (user ID) as that of the data selected particle 211 and multiples the particle size Psize by C2 (C2<1) as for the particle 211 having the data attribute (user ID) different from that of the data selected particle 211 as described with reference to FIG. 12.

On the other hand, in a case where it is determined at step S22 that the data selection operation is not performed, the procedure shifts to step S24, and the processing unit 93 changes the particle size Psize of each particle 211 of the particle stereoscopic image according to the lapse of time as described with reference to FIG. 11. The amplitude of the particle size Psize differs according to the data attribute (swing speed) of the corresponding shot data.

At step S25, the processing unit 93 displays the particle stereoscopic image obtained by drawing each particle 211 in the particle size Psize determined by the processing at step S23 or S24 in the particle display area 212.

At step S26, the processing unit 93 determines whether to finish displaying. For example, in a case where it is detected that the user performs operation to finish the display control processing of displaying the shot data in particle representation and the like, it is determined to finish displaying.

In a case where it is determined that the display is not finished yet at step S26, the procedure returns to step S22 and the above-described processing at steps S22 to S26 is repeated.

On the other hand, in a case where it is determined at step S26 that the display is finished, the data selection display change processing is finished.

As described above, according to the data selection display change processing, the particle stereoscopic image in the particle display area 212 is changed depending on whether or not the data selection operation of specifying the predetermined particle 211 of the particle stereoscopic image displayed in the particle display area 212 by the cursor 213 and pressing the predetermined operation button is performed.

In a case where the user performs the data selection operation, the particle 211 of the same data attribute (user ID) as that of the data selected particle 211 is emphasized. This makes it easy to observe the shot data focusing on the particle 211 having the same data attribute (user ID) as that of the predetermined particle 211.

In a case where the user does not perform the data selection operation, the amplitude of each particle 211 dynamically changes according to the lapse of time and the predetermined data attribute (swing speed). In addition to indices of the swing type and the ball speed of each shot data represented by the pie chart, still another index (swing speed in this embodiment) may be represented by the amplitude change of the particle size Psize, so that it becomes easy to observe a large number of shot data.

Therefore, according to the data selection display change processing, enormous data may be displayed so as to be understood easier.

Meanwhile, in the above-described example, different data attributes are adopted as the data attribute (swing speed) during the data selection operation and the data attribute (user ID) during the data non-selection operation; however, the same data attribute may also be adopted.

In addition, in the processing at step S23, the particle size Psize of the particle 211 having the same attribute as the data attribute of the data selected particle 211 is enlarged and the particle size Psize of the particle 211 having the different attribute is reduced; however, it is possible that the processing unit 93 only enlarges or reduces.

Also, in the above-described example, the swing speed is adopted as the data attribute represented by the amplitude change of the particle size Psize during the data selection operation at step S24; however, the data attribute other than the swing speed may also be adopted.

Similarly, at step S23, the user ID is adopted as the data attribute for enlarging or reducing the particle size Psize; however, the data attribute other than the user ID may also be adopted.

For example, as the data attribute adopted in the processing at steps S23 and S24, the user may set an arbitrary data attribute from the setting screen.

<S. Another Example of Particle Stereoscopic Image>

Next, another particle stereoscopic image which the processing unit 93 may display in the particle display area 212 is described.

Assuming that the particle stereoscopic image in which the particles 211 are stereoscopically distributed on the side surface of the conical shape as illustrated in FIG. 4 is the first particle stereoscopic image which the processing unit 93 may display, the processing unit 93 may generate at least three types of particle stereoscopic images which are a second particle stereoscopic image in addition to the same and a third particle stereoscopic image and display them on the display 51. The type of the particle stereoscopic image displayed in the particle display area 212 may be arbitrarily set by the user from the setting screen, for example.

<8.1 Second Particle Stereoscopic Image>

FIGS. 15 and 16 illustrate an example of the processed image 301 in which the second particle stereoscopic image is displayed in the particle display area 212.

In the processed image 301 in FIGS. 15 and 16, a configuration other than the particle stereoscopic image displayed in the particle display area 212 is similar to that of the processed image 201 in FIG. 4 or the like, for example, so that, the description thereof is omitted.

In the particle display area 212 in FIGS. 15 and 16, the particle stereoscopic image in which the respective shot data are stereoscopically distributed in a three-axis distribution diagram using the particles 211 with one axis assigned to the swing speed, one axis assigned to the ball speed, and one axis assigned to the ball spin is displayed.

The viewpoint of the particle stereoscopic image displayed in the particle display area 212 is different between FIGS. 15 and 16. The viewpoint of the particle stereoscopic image may be changed by operating the mouse and the controller of the input unit 92.

For example, in the processed image 301 in FIGS. 15 and 16 also, in a case of color display, the particles 211 are drawn in different colors for each swing type, and in a case of monochrome display (gray display), they are drawn in different gray values for each swing type. As a result, a ratio of data for each swing type may be understood at a glance.

In addition, the size of the particle 211 is determined by the particle size determination processing in FIG. 8. As a result, the particle size Psize is determined according to the number of shot data to be displayed and the space size of the particle display area 212, so that it is possible to display in unified density regardless of the number of data.

Furthermore, while the processed image 301 is being displayed, the above-described data selection display change processing is executed. As a result, in a case where the user does not perform the data selection operation, the amplitude of each particle 211 dynamically changes according to the lapse of time and the predetermined data attribute (for example, swing speed). On the other hand, in a case where the user performs the data selection operation, the particle 211 of the same data attribute (for example, user ID) as that of the data selected particle 211 is emphasized. Therefore, it is easy to discriminate the data having the same data attribute.

<8.2 Third Particle Stereoscopic Image>

FIGS. 17 and 18 illustrate an example of the processed image 321 in which a third particle stereoscopic image is displayed in the particle display area 212.

In the processed image 321 in FIGS. 17 and 18, a configuration other than the particle stereoscopic image displayed in the particle display area 212 is similar to that of the processed image 201 in FIG. 4 or the like, for example, so that the description thereof is omitted.

In the particle display area 212 in FIGS. 17 and 18, the particle stereoscopic image in which a face surface of a tennis racket is formed in a plane including two axes, an axis perpendicular to the face surface is assigned to the ball speed, and the respective shot data are stereoscopically distributed on the face surface by using the particles 211 is displayed.

In the particle stereoscopic image in FIGS. 17 and 18, the particle 211 is arranged in a corresponding area on the face surface on the basis of the information regarding the hitting position of the play data obtained from the server 13. A plurality of particles 211 arranged in the area corresponding to the hitting position is uniformly dispersed in the area. In the height direction perpendicular to the face surface, it is arranged in a higher position as the ball speed is faster on the basis of the value of the ball speed, and a distribution shape in an area unit is a quadrangular pyramid shape.

In FIGS. 17 and 18, the viewpoint of the particle stereoscopic image displayed in the particle display area 212 is different. The viewpoint of the particle stereoscopic image may be changed by operating the mouse and the controller of the input unit 92.

In the processed image 321 in FIGS. 17 and 18 also, the particles 211 are drawn in different colors for each swing type in color display, and drawn in different gray values for each swing type in a case of monochrome display (gray display), for example. As a result, a ratio of data for each swing type may be understood at a glance. Also, since the position corresponds to the ball speed in the height direction, tendency of the ball speed for each swing type may be understood at a glance.

In addition, the size of the particle 211 is determined by the particle size determination processing in FIG. 8. As a result, the particle size Psize is determined according to the number of shot data to be displayed and the space size of the particle display area 212, so that it is possible to display in unified density regardless of the number of data.

Furthermore, while the processed image 321 is being displayed, the above-described data selection display change processing is executed. As a result, in a case where the user does not perform the data selection operation, the amplitude of each particle 211 dynamically changes according to the lapse of time and the predetermined data attribute (for example, swing speed). On the other hand, in a case where the user performs the data selection operation, the particle 211 of the same data attribute (for example, user ID) as that of the data selected particle 211 is emphasized. Therefore, it is easy to discriminate the data having the same data attribute.
